In this study, high spatially resolved surface plasmon resonance (SPR) sensing is achieved by employing a cap-shaped gold nanoparticle based film. Unlike conventional SPR detecting gold films, this unique film is not sensitive to angular change and relies solely on wavelength shift for SPR sensing. This capability allows optics of large numerical aperture and thus greater spatial resolution.
